Reynolds Mold Max® 29NV Low Viscosity Tin Cure Silicone Rubber Compounds
Categories:	Polymer; Thermoset; Silicone; Silicone Rubber
Material Notes:	Product Overview: Mold Max™ 14NV and 29NV are tin-catalyzed silicone rubbers that offer low viscosity, fast cure and long library life. Mold Max™ 14NV and 29NV do not require vacuum degassing. Mix ratio is 100A:10B by weight. Pot life is 40 minutes. Cure time of 14NV is 4 hours at room temperature, cure time of 29NV is 6 hours at room temperature. Mold Max™ 14NV and 29NV will reproduce the finest detail and are suitable for a variety of industrial and art related applications including making molds for reproducing prototypes, furniture, sculpture and architectural elements. Cure time can be reduced with Accel-T™ cure accelerator. Mold Max™ 14NV and 29NV can be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins. Important; Do not cast concrete into rubber molds made with this product. Concrete will not cure properly and inhibition will result. Important; you must weigh Part A & B components using a gram scale to be successful with Mold Max™ 14NV and 29NV. Information provided by Reynolds Advanced Materials
